Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed January 14, 1907. Serial No. 352,203.

To all whom it may concern:

Be it known that I, MASCHIL D. CONVERSE, a citizen of the United States, residing at Newark, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Closures for Jars, Bottles, and Like Receptacles, of which the following is a specification.

My present. invention relates to metallic closures designed more particularly for bottles, jars and other like receptacles, from which the contents, after unsealing, are usually dispensed or removed fractionally or intermittingly, thus making it desirable that the closure should be manually readjustable or re-sealable, and with sufiicient force to effectually prevent spilling of the contents of the receptacle in case of its overturning, and also to keep insects from entering or odors from escaping.

More definitely, this invention therefore belongs to the type of closure of which my'application for Letters Patent of the United States, filed January 14th, 1907, Serial No. 352,202 is an example, and the objects of my invention are, in addition to the foregoing requirements. which it fully meets, to provide a very simple, neat and inexpensive closure for such purposes.

My present invention is adapted to be used in certain novel combinations with lmown and other forms of constructionof cap members of closures which require circumferential retaining bands whereby these several objects are attained; but the leading feature resides in the use of a novel unsealing and re-sealing lock-lever mechanism developed integrally at the jointure of a clamping band, said ends being united by a lock-seamlike fold, made with the outer ply thereof greatly widened or extended circumferentially, to form such integral lever, to serve for easy and expeditious unfolding of the same to unseal a receptacle, without the use of any implement, and whereby, also, great clamping force can be manually exerted to reseal by re-folding of the same, all which will hereinafter be fully set 1 forth and definitely claimed.

In the drawings: Figure 1, partly sectional, represents an arrangement of parts including an unflanged, clamping band, with the circumferentially widened integral lock-lever and lock-seam hereinbefore mentioned, which, combined, show the adaptation of my present invention to one form of cap member complete and applied to a receptacle. Figs. 2 (an underside view before being so applied) and 3 (a side elevation of Fig. 1, with the clamping band removed) show the construction, arrangement and operation of this adaptation and combination of my invention. Figs. 4 (a side elevation, partly sectional, before sealing), 5 (an underside view of Fig. 4), 6 (a top view of Fig. 4), and 7 (a side view similar to Fig. 4,partly sectional, after sealing of the receptacle), represent a different arrangement of parts, including a flanged, clamping band, with the widened or circumferentially extended integral lock-lever and the lock-seam hereinbefore mentioned, which, combined, show the adaptation of my present invention to another form of cap member complete, which figures, together with the preceding ones, will enable those skilled in the art to fully understand the nature and operation of my invention as the ceptacles in the initial sealing of the latter is by pressure and mechanical means now commonly employed; that described in Letters Patent No. 7 51,335 dated February 2d, 1904 and No. 751,404 dated February 2d, 1904, and respectively issued to Frank C. B. Page, being an example.

Like letters indicate corresponding parts throughout the several figures. U;-

A, is a metallic cup or cap of ductile metal, having its depending flange divided vertically in a plurality of places, a, a, (1 (Figs. 1, 2 and 3), adapted to inclose a disk of cork or other suitable sealing medium. This cap is substantially equivalent, both in construction and operation, to a like part described in my said application hereinbefore referred to, and is made a part of my present invention, not broadly, but in a novel combination therewith which will be further shown.

B, is an unflanged, clamping band, having its ends united by a lock-seam, the outer ply, b, of which is widened or extended circumferentially of the band to form an integral lock-lever, E, by which the seam may be manually unfolded with ease, and without the use of any implement to unseal the closure, and whereby also sufficient clamping force can be exerted to reseal the receptacle by simply manually operating the lock-lever thus re-folding of the lock-seam, which will be readily understood by examination of the several figures.

The lifting up of the lock-lever elongation, E, of the lock-seam members of the band, B, as shown in Fig. 2, releases its circumferential embrace on the divided sections of the depending flange of the cap, A, so that it is removable therefrom when the underturned edge, o of these, one by one, may then easily be disengaged from the shoulder, d of the receptacle, D, the ductile metal bending across at e (Fig. 3), and unsealing or .opening of the receptacle thus be accomplished. To

re-seal, this procedure is reversed, and both unsealing and re-sealing in the case of the application of my invention shown by Figs. 4, 5, 6 and 7, are accomplished by means of the integral lock-lever extension, E, of the lock-seam members operating in the same manner.

In this latter application of my invention I have shown a flanged, clamping band with the same form of integral extended lock-lever, E, to control the lockseam, the upper flange, b of the clamping band, B (Figs. 4, 5, 6 and '7) serving to engage the peripheral margin of a cap, A, of known type in which is inclosed a disk of cork or other suitable sealing medium, the

lower edge of the band, B, in this case depending below the shoulder, d of the receptacle, D (see Fig. 4), prior to its being by mechanical means initially turned under the shoulder, as at b in Fig. 7.

Manually unsealing and re-sealing, in case of this application of my invention, are accomplished because respectively oi the expanding and contracting of the clamping band, B, as before and its upper and lower flanges, b 5*, due to the action of the lock-seam members, effected by manipulation of the said novel ex tended integral locklever, E, thereof, in the same manner as in the before-named application.

Having described my invention, what 1 claim as new and desire to secure by Letters Patent, is:

In a manually unsealahle and re-sealable meiallie elosnre of the class described, adapted to he initially applied to a'receptaele as set forth, a cap, adapted to inelose a sealing medium, and a ductile, eircumferential clamping band, having its ends joined by a l0eksea1n the outermost ply of which is circumferentially extended to form a lever for manually opening and closing of said loelescam.

In testimony whereof I have s "ned my name to this specification in the presence. of two subscribing witnesses.
